How to read this page
Each race below shows the share of valid ballots the marginal elected candidate actually won, and compares it to the proportional quota: the share they'd need to clinch the seat under any proportional voting method (1 seats + 1). For a 1-seat ward the quota is 50%; for 2 seats, 33.3%; for 3 seats, 25%.
Where the actual winning share fell below the quota, we show the signed gap as points below quota (a negative number) — the editorial indictment. Above-quota results clear the bar and pass without comment. The voting method is the subject of every observation here. Named candidates appear as the public election record requires; the cause being audited is the voting method, not the individuals. See the methodology page for derivations.
If votes were counted by party
Across the 1 ward in this cycle, parties received the vote totals below. The proportional column shows what each party would have won if the 3 seats had been shared out in proportion to votes received (how, with caveats). The Δ column is the actual seat count minus the proportional seat count — positive numbers are parties First-Past-the-Post over-represented; negative are parties it under-represented.

| Conservative Party | 8,216 | 54.4% | 3 | 100.0% | 2 | 66.7% | +1 |

Vote share vs seats won
The top bar is each party's share of votes cast in this council. Below, one square per seat, coloured by the party that won it — first the actual First-Past-the-Post result, then what a proportional method would have produced from the same vote totals. Divergence between the bar and the actual grid is the indictment of the method.
Council composition: what this election replaced
